This patch reduces paint events by removing code which sets native
widgets dirty in QWidgetWindow::handleExposeEvent. Native widgets are
also marked dirty in QWidgetPrivate::drawWidget, so it is enough for
proper painting.
This restores Qt4 behavior when one resize means one repaint for native
widgets. Without this patch the native widget is marked as dirty on
every expose event, so one repaint is from syncBackingStore and second
(or more) is from marking the widget dirty explicitly.
This patch improves performance of native widgets and it also reduces
locks when paint event is v-synced, e.g. on OpenGL swap buffers or on
any other technology like VDPAU, VA-API, etc.
Added autotest for checking number of paint events for native widgets.

The fallback code for unhandled event types in QWidgetWindow::event
directly called event() on the underlying QWidget (i.e. m_widget->event(e)).
The problem with that approach is that it does not activate any
event filters that can have been installed on the top level widget.
Instead, let's use sendEvent to forward the event to the widget.
An extra modification becomes necessary:
the events received when creating/showing/etc. a widget change,
hence the corresponding test needs to be tuned. On the other hand,
apparently this fixes a long time XFAIL in that test.

Change childWidget->windowHandle() to childWidget->internalWinId() in
q_createNativeChildrenAndSetParent() to determine whether should we call
childWidget->winId().
This is because in some circumstances Qt will crash due to accessing
deleted QWidgetWindow object if we use windowHandle(). Think about the
following scenario:
1) create a widget A without parent and add two child widgets B and C to A
2) create a native widget D as the child of B, note that when we set
Qt::WA_NativeWindow attribute to it, its QWidgetWindow will be created
which means its windowHandle() is not null.
3) create a top level widget E as the child of C and show it. This will
make Qt call createWinId() to A and then
q_createNativeChildrenAndSetParent() will be called to create A's native
children recursively and finally make D's QWidgetWindow object become a
child of A's QWidgetWindow object. Please note here that B will not become
a native widget just because at that moment windowHandle() of D is not
null and Qt will not call winId() to its parent B
4) Set A's parent to another widget which has been shown, setParent_sys()
will be called to A and then Qt will call destroy() to A. in destroy() Qt
will try to call destroy() to its children recursively with a condition that
the child has Qt::WA_NativeWindow been set. But D's parent B is not a native
widget right now so B and D is not destroyed. Qt will then deleted the
QWidgetWindow object of A, since E's QWidgetWindow object is a child of
A's QWidgetWindow object, it will also be deleted. Now E hold a deleted
pointer of QWidgetWindow object. This is the source of crash later.

Qt::WA_Mapped maps (sic) to windowHandle()->isExposed(), and we set/update
it in QWidgetWindow::handleExposeEvent(). Setting it directly in show_sys
shortcuts QPA and assumes showing a window is synchronous on all platforms,
resulting in trying to flush the widget backingstore when the window was
not exposed yet (due to discardSyncRequest starting to return false).

This increases consistency a lot: all windows and dialogs from a Qt
application will show the app display name in the caption, on Windows and X11.
This helps identifying which app a dialog belongs to, which is especially
useful when the dialog is very generic and shows up unexpectedly.
For compatibility reasons, the app name is added to the caption only
if setApplicationDisplayName() was called -- or if the caption would be
completely empty. The standard Qt4 case (setWindowTitle + no display name)
is unchanged.

A virtual method was reimplemented to return an always-empty string,
probably a leftover from a refactoring.
This fix showed that tst_qwidget_window was buggy: between Qt4 and Qt5,
a "Before" became "After", which made "Before" unused, and was masking
the fact that the app name was empty by default. In addition, the
earlier Qt5 change that made the app name default to argv[0] now requires
updating this test, now that it's actually working.
